ARTHUR LIPSOIIUTZ, OF CHICAGO, ILLINOIS.

SIDE FRAME FOR CAR-TRUCKS.

To all whom, it may concern.-

Be it known that I, ARTHUR LIPSOHUTZ, a citizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented a certain new, useful, and Improved Side Frame forCar-Trucks, of

description, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to car trucks and has special reference toimprovements in trucks of that class wherein the journal boxes arerigidly secured in the truck side frames and wherein the bolster issupported by springs in or upon said side frame. In a truck of thisclass, the truck bolster is usually of its ends extend through or beyondthe side frames, the bolster springs being arranged substantially in thevertical planes of the side frames.

The object of my invention is to improve the construction of the sideframes of cartrucks of the class mentioned, and the particular object ofthe invention is to provide an improved cast steel side frame for cantrucks; further, to provide an improved cast steel side frame that shallbe composed of only two parts, ,both structurally simple, and which maybe manufactured at less than the usual cost of car-truck frames.

Other objects of my invention will appear hereinafter.

My invention consists generally in a cartruck side frame characterizedby a single piece lower or tension member having integral bolstercolumns, in combination with a single piece upper or compression memberthat is rigidly secured to the ends of said ten sion member and also tothe tops of said columns.

The invention also consists in a car-truck side frame of the foregoingdescription, which is provided with brake-hanger brackets, which areintegral with one of said members.

My invention further consists in various details of construction and incombinations of parts, all as hereinafter described, and particularlypointed out in the claims.

My invention will be more readily understood by reference to theaccompanying Specification of Letters Patent.

Application filed November 5,

drawings, forming a part of this specification, and in which Figures 1,2, and 3 are side elevations of three car-truck slightly differentside-frames, all embodying my invention, onehalf of the bolster and thebolster springs being omitted in each figure; Figs. 4, 5, and 6, arevertical sections on lines tta of Fig. 1, bb of Fig. 2, and c--c of Fig.3, respectively, the bolsters and springs being omitted, for clearnessFig. 7 is a top plan view of the side frame shown in Fig. 3; Fig. 8 isa-perspective view of the inner side of one of my improved side frames,whereof the upper frame member is provided with. integral brake-hangerbrackets; and Fig. 9 is a similar view showing brake-hanger bracketsformed upon the lower member of the side frame.

As shown in the drawings, 11, represents the wheels of a car truck 2 2,the axles; 33, the journal boxes; 4, the bolster; 4, the bolster guidessecured upon the bolster; 55, the bolster springs; and 6, a bottom tiebar.

The parts of the car truck here mentioned may be of any suitable form orconstruction adapted for employment with a rigid side frame.

Each of the three side frames herein shown comprises two members, one alower, or tension member, adapted to rest upon the tops of the journalboxes and the other, an upper, or compression member, which is fastenedupon the tension member. In all casesthe middle portions constitutingthe bolster columns are integral with the tension member. Yet these sideframes which correspond in general description differ in details; henceit is necessary to consider and describe them separately.

The novel side frame shown in Figs. 1 and 4 has a tension member A,adapted to rest upon the tops of the boxes 3, 3, and having its centralor middle portion depressed to about the level of the bottoms of saidboxes. The member A is a metal casting and the bolster columns CC areintegral therewith. These preferably, though not necessarily, rise to aheight slightly above the tops of the journal boxes. The top orcompression member B of the side frame is of the same length asthetension member. It also is preferably a steel casting, but may be awrought metal bar of suitable cross section.

bolted or riveted to the member A and is se cured to the boxes in theusual way. Upon the removal of the compression member the bolster andsprings may with case be placed in or removed from the frame. The springseat may be formed by the spring plank 7, preferably a channel beam, asshown in Figs.

1 and 4, in which case the member is provided with securing ears or lugsc; or the central part of the member A may be extended, laterally toform an integral spring seat D as shown in Figs. 3, 6, and 7.

The side frame shown in Figs. 2 and 5, comprising members ACB, differsfrom that above described in that the com pression member'B" is shorterthan the tension member. The member A is provided .with inwardlyprojecting portions A, substantially in the plane of its ends and tothese projections I secure the member B by bolts 1). The central portion13 of the bar B is preferably thicker, providing shoulders which engagethe tops of the columns and aid the bolts 6 in holding the columns inplace. This feature may also be employed in the first frame if desired.As in the latter case the side frame of Fig. 2 may contain a springplank 7 or have an integral spring seat, as best suited to the othermembers of a particular car truck.

' Passing to the device shown in Figs. 3 and 6, it will be found to beidentical with the frame next above described except that the tensionmember A is provided with notches or recesses A wherein'the ends of thecompression member are secured by bolts b and the integral spring seat Dis shown on the tension member. The middle portion of the compressionmember and the columns C remain as before. I find the abutment of thecompression member with columns and tension member to be mostadvantageous and prefer this form to others.

A further feature of my invention is disclosed in Fig. 8 wherein I haveshown the brake-hanger brackets G which I cast directly upon the innerside of the com ression member. While it is desirable to orm thesebrackets upon the member which is of most simple configuration, Inevertheless sometimes elect to form the same on the inner sides of thecolumns C, as shown in Fig. 9, see G.

Various modifications of my invention will readily suggest themselves toone skilled in the art hence I do not confine or limit the said tensionmember and upon the tops of columns; substantially as described.

2 The herein described improvement in car trucks, comprising a two-partside-frame adapted to rest upon the tops of the journal boxes, the lowerpart of said frame being provided with bolster-guiding columnsintegrally joined thereto at their lower ends only and the upper part ofsaid frame being detachably secured to the ends of said lower part andalso to the upper ends of said columns; substantially as described.

3. A car truck side-frame comprising two parts, to-wit, an upper and alower member, said lower member being provided with a spring-seat andalso with a pair of upwardly extending bolster guiding columns integraltherewith; said upper member being secured to the ends of said lowermember and to the otherwise free upper ends of said columns;substantially as described.

4. A car truck side-frame composed of an upper and a lower member, saidlower member being provided with two upwardly ex tending integralbolster guiding columns, one of said members being provided withintegral brake-hanger brackets, andv the upper member being bolted tothe endsof the lower member and also to the upper ends of said columnssubstantially as described.

5. A car truck side frame comprising an upper and a lower member; saidlower mem ber being adapted to support the truck springs and havingelevated ends -to rest upon the journal boxes of the truck and beingprovided with a pair of upwardly extending columns, integrally joined tosaid member at their lower ends only; and said upper member being boltedto the ends of said lower member and to the upper ends of said columnsand depending between said columns; substantially as described.

6. A car truck side frame comprising an upper and a lower member; saidlower member having ends adapted to rest upon the journal boxes of atruck and being, provided with columns, integrally joined to said lowermember at their lower ends only; said upper member being secured to theends of said lower member and to the upper ends of said columns andprovided with shoulders engaging said upper ends of said columns substantially as described.

'7. A two-part side-frame for car trucks,

cured upon and to the ends of said tension member and to the upper endsof said columns substantially as described.

8. A car truck side-frame comprising an upper and a lower member, saidlower member being provided with integral bolster columns and withinward projections adapted to receive the ends of the upper framemember, and said upper member being of less length than the lower memberand secured on said projections and also to the upper ends of saidcolumns; substantially as described.

9. The two-part side-frame comprising a tension member having adepressed middle portion and raised ends and provided with bolstercolumns integrally joined thereto at their lower ends only, said memberhaving recesses and shoulders near its ends, in combination with acompression member secured to the upper ends of said columns and havingits ends secured in abutment with the shoulders on the ends of thetension member substantially as described.
